An estimated gestational time was calculated for 163 of 220 terminations for which gestation was not reported:

For the 163 terminations without gestational age, the date of the last menses and date of termination was used: 7 (4.3%) occurred at less than 6 weeks; 77 (47.2%) occurred at 6 to 8 weeks; 68 (41.7%) occurred at 9 to 12 weeks; 10 (6.1%) occurred at 13-15 weeks; and 1 (0.6%) occurred at 16 weeks.

Of the 163 terminations without gestational age, 16 had the month but not the day of the last menses. These were estimated using the 15^th day of the month.

For the remaining 57 terminations, the month of the last menses was unknown for 56 and the month of termination was unknown for one and an estimated gestation could not be calculated.
